The A.C. motor measured 40 inches long and30 inches in diameter and the power leadswere left standing in the air - no externalpower source!

He then went to a local radio store andpurchased a handful of tubes (12), wires andassorted resistors. A box measuring 24inches long, 12 inches wide and 6 inches highwas assembled housing the circuit.

The box was placed on the front seat and hadits wires connected to the air-cooled,brushless motor. Two rods 1/4" in diameterstuck out of the box about 3" in length."

The mention of this experiment in a local paper kindof blew me away but it did give "some" detail of

what was in this mysterious power box.

We know that T.H. Moray had probably the bestknown version of such a device. In his case he useda special "valve" which appeared to be basically a

diode. Except this diode worked more like a Triac.That is, any electrical wave, both positive ANDnegative going currents, was picked up by anantenna and passed through this diode with minimalloss of energy. As far as we know, this valve wasbased on a composite substance with GERMANIUMas the host material.

From there it went through a tuned circuit based onvacuum tubes and capacitors to build and dischargethe energy as demanded by the load.

The tuned circuits were resonant with one or moreearth or cosmic frequencies and the vacuum tubesacted as harmonic constructive interferenceamplifiers of the input signals.

We will note that Moray's resonant circuits usedCAPACITORS, COILS and RESISTORS. Experimentsdone during Moray's heyday showed an output up to50,000 Watts of high frequency energy. It isbelieved that the energy was high frequencybecause 100 watt light bulbs burned cool to thetouch.

One other CRITICAL POINT about Moray's converterwas that it would ONLY energize RESISTIVE loadsand NOT INDUCTIVE loads. This is because inductiveloads imply coils of wire which are heated more soby HYSTERESIS (interferring electro-magneticfields) rather than simple resistance from the flowof current through molecular/atomic patterns.

This type of interferring field caused an energy

backup and subsequent de-tuning of Moray'sgenerator. Since it was essentially a TUNED device,it could not compensate for any frequency changesor distortions ONCE TUNED. As a result, any attempt

to hook up an inductive load would cause the deviceto stop generating electrical energy. To restart it, allinductive loading must be removed, the device re-tuned and restarted.

Moray also used an unusual mode of operation for avacuum tube in that he operated with a "coldcathode." This did not require a heated plate for the

There is also mention of radioactive elements in theantenna circuit which leads one to think he mighthave been tuning into the continual radioactivedecay processes of nature, rather than cosmic orearth energies.

Now to the Tesla Power Box

We will first of all note the use of an AC coil motor.This alone tells us that the Tesla device wassuperior and not so dependent on tuning as wasMoray's machine which could only power RESISTIVEloads. All universal energy moves in WAVES and sois essentially for alternating current (AC). That iswhy Moray called his book "THE SEA OF ENERGY INWHICH THE EARTH FLOATS". The entire universe iscontinually bathed in these AC energies and theycover the entire frequency spectrum.

What intrigues the hell out of me was how Teslacould use "off-the- shelf" vacuum tubes and othercomponents, put them together in the correctconfiguration and make it work.

So, in the case of the Tesla Power Box, he eitherwound his own coils or simply used the wire toconnect the resistors with the vacuum tubes. I amof the opinion that he used the wire ONLY forconnection and DID NOT USE COILS! I also think heused a DIODE somewhere in the circuit in order totap ONLY one polarity.

We have no specifications for the AC motor thatTesla used in the auto, so we have no idea if it wassingle or polyphase. In the case of a single phasemotor, it only requires a single winding whichprojects a magnetic field that rotates according tothe increase or decrease of the alternating current.

A polyphase (poly = two or more) motor uses

multiple windings which are fed by phased inputcurrents that alternate in such a manner as to

reinforce each other. In the case of a 3 phase motor,the currents are phased 120 degrees apart. Thisgives much greater torque to the motor but requires3 times the current because it uses 3 times the input

energy.Since the box powered an AC (coil) motor, it isprobable it was TUNED to one or more frequencies,most likely polyphased frequencies.

So, if the 3" long rods were in fact ANTENNAS, wecan calculate their frequency by using the following :

This would indicate the 3" rods (if they were truly 3"in length and functioning as antennas) wouldresonate at 246 MHZ.

Because of the parts list description, I am of theopinion that it was a DUAL circuit. That is, 6 vacuumtubes and one 1/4" diameter 3" rod along withassorted resistors were to pick up and "pump" ONLYthe positive going signals, while the other 6 vacuumtubes, rod and resistors did the same for thenegative going signals. Such a scheme could eitheruse PARALLEL or SERIAL connections of the vacuum

tubes. Since current conduction is proportional tosurface area, one would think that a parallel

arrangement of the 70L7-GT rectifier beam powertubes with all INPUTS connected to one antennasource and all OUTPUTS connected to a commonterminal attached to the load, would provide for the

MAXIMUM current flow from incoming energywaves.

The nature of these "energy waves" is the questionhere. Are they cosmic rays, electrostatic, Schumannpeaks, magnetic force, something "other" or Aetherflow into the neutral centers of mass as per Keely.

Vacuum tube construction takes several forms. Ofthese, the simplest is two plates separated by a gridwire. When the bottom plate is heated, thermallyinduced ions (thermionic emissions) are emitted bythe bottom plate. The grid can be biased by theapplication of voltage to increase, decrease or haltthe flow of these ions to the upper plate.

Other forms include more plates with more grids toallow better control of the ion flow. By properbiasing, vacuum tubes can be operated as switches,modulators or amplifiers among other uses.

Vacuum tubes operate primarily with high voltagesthat control the ion flows. Modern transistors areequivalent to vacuum tubes except that they operateusing CURRENT instead of voltage. Transistorsequate to Vacuum tubes by the followingcomparisons :

In the case of the Tesla Power Box, the vacuum tubeappears to function as a "pump", collecting

incoming current in the form of ion intensification.Once this "compressed" ion field reaches a certaindensity, the pump allows it to be released into thenext stage of the circuit, be it the actual load or

another vacuum tube.So if the circuit is 6 vacuum tubes in parallel, all fedfrom a common antenna, outputting to a commonload terminal, then the common antenna inputwould feed all vacuum tubes with the same wave.This would give the greatest CURRENT accumulationbecause of the EXPANDED SURFACE AREA of the

paralleled tubes.Note, these vacuum tubes most likely operate in the"cold cathode" mode since the heaters of thevacuum tubes were not fed by any outside voltageto provide the heat for the more orthodox therionicemission.

If the vacuum tubes are hooked in series, then one"pump" would feed another "pump" to getsuccessively higher densities of electrons. Thiswould give higher VOLTAGES because of increasedPRESSURE.

Keep in mind that electricity is much like air orwater. We can think of voltage as pounds per squareinch (PSI) and current as cubic feet per minute(CFM). That is PSI is pressure, CFM is flow.

Another analog is comparing a river to electricity. Insuch a comparison, the speed of the river is theVOLTAGE or pressure while the width of the river isthe CURRENT or rate of flow.

Such a comparison shows WHY current requires THE

GREATEST SURFACE AREA for the maximum flow.Fuses function on just this principle, when the

current flows over the surface of the fuse, it createsheat. If too much current flows, it creates too muchheat causing the fuse to melt and separate. Themore surface area the fuse, the greater the amount

of current can flow, another reason to not place apenny in a fuse socket.

So we have two antennas (1/4" diameter, 3" longrods), two sets of 6 vacuum tubes connectedtogether by wire and assorted resistors. As thewaves of energy are collected by the 3" rods,positive on one, negative on another, the energy

builds up in the form of increased ions in each of theparalleled vacuum tubes. As in Moray's generator,the circuit will feed whatever load is attached aslong as it does not EXCEED the current carryingcapacity of the circuit components. What we have isan energy pumping system.

I made a drawing of the box with some idea of the

circuit. My electronics knowledge is on IC's andtransistors with almost nothing in regard to vacuumtubes so there won't be much technical concept ofthe circuit per se. Perhaps after some study, either Ior someone else will come up with some testable oruseable circuits.
